Multi-functional filtering and dust falling box

Abstract

The invention discloses a multi-functional filtering and dust falling box which comprises a dust box main body (8), a dust falling plate (2), a separating hole plate (5), a one-time dust separating box (10), a second-time dust separating box (4), a third-time dust separating box (9) and an air steam filtering device (6). The dust box main body (8) is of a multi-layer box-type structure, the one-time dust separating box is located on the bottommost layer and communicated with a dust inlet, and the dust falling plate (2) is located on the upper portion of the dust inlet formed in the one-time dust separating box; the second-time dust separating box is located on the one-time dust separating box, and the separating hole plate (5) is arranged in the second-time dust separating box; the third-time dust separating box is located on the second-time dust separating box, the air steam filtering device is arranged in the third-time dust separating box, and an outlet of the air steam filtering device is communicated with an air inlet interface (7) of a draught fan. The multi-functional filtering and dust falling box integrates dust sucking, dust falling and dehumidifying into a whole. The problems that a traditional pure-suction-type dust suction vehicle is low in dust suction efficiency and cannot be operated in a humid environment and on a rainwater road surface for a long time are solved, and the purpose of improving the operation efficiency and being free of secondary flowing dust pollution, simple in structure, few in wear-out parts, convenient to use and maintain and easy to operate are achieved.

Description

technical field [0001] The invention belongs to the technical field of pure suction trucks, and mainly relates to a multi-functional filter and dust suppression box for a vacuum truck. It is widely suitable for cleaning and dust removal in squares, highways, residential quarters, parking lots, docks, airports, stations, cement factories, power plants and other places. Background technique [0002] At present, people have a better understanding of the relationship between human health, life expectancy and inhalable particulate matter. Studies have proved that particulate matter with a size of about 10 μm (PM-10 for short) and <10 μm may cause death of premature infants and respiratory diseases. In addition to doing its job, it must at least ensure that the number of particles in the air is controlled and must not cause an increase. [0003] The pure suction vacuum cleaner is a new product developed with modern technology. It has changed the traditional way of sweeping wi...
